There are two “high-level” types of caching: server-side and client-side. Once you grasp and apply the concept to your own projects, the days of telling your clients to “hard refresh” will be over. I’m talking about cache-busting, and it’s a lot less intimidating than it sounds. The good news is, a problem like this is totally within your control to resolve.
The bad news is, it’s kinda your fault this is happening, and your anger is misguided. You’ve flipped your table in rage, and vented to your colleagues about how technically-stupid your client was for not seeing the same things as you did? You’ve told them to “hard refresh,” and it didn’t help? You’ve clicked the “Delete Cache” button in the WordPress admin, with no effect? Some of them are listed in the table below.įor a detailed list of names that can be used in place of the $handle parameter, see wp_register_script().Have you ever made a change to a CSS or JavaScript file on a client’s website, but your client reports they can’t see the changes? Top ↑ Default Scripts and JS Libraries Included and Registered by WordPressīy default, WordPress installation includes many popular javascript libraries and scripts commonly used by web developers besides the scripts used by WordPress itself. Uses global: ( unknown type) $wp_scripts.Uses: WP_Scripts::add(), WP_Scripts::add_data() and WP_Scripts::enqueue().This is useful to keep in mind when debugging ancient themes. This means that it may not work with a few very old themes that do not call these functions. This function relies on the use of wp_head() and wp_footer() by the active theme.jQuery UI Effects is not included with the jquery-ui-core handle.Instead, use wp_deregister_script() and register the script again with the new parameters. If you try to register or enqueue an already registered handle with different parameters, the new parameters will be ignored.Calling it outside of an action hook can lead to problems, see the ticket #11526 for details. For the login screen, use the login_enqueue_scripts action hook. To call it on the administration screens, use the admin_enqueue_scripts action hook. The function should be called using the wp_enqueue_scripts action hook if you want to call it on the front-end of the site, like in the examples above.
#WP ENQUEUE SCRIPT WAS CALLED INCORRECTLY WORDPRESS CODE#
While the intended (delayed) strategy passed by the code author may not be the final one, it will never be a stricter one, thus maintaining the integrity of the dependency tree. When applying a loading strategy via either the wp_register_script() and wp_enqueue_script() functions, the scripts dependency tree is taken into consideration and the most eligible loading strategy is applied. The same approach applies when using wp_register_script(). Such scripts may execute either before the DOM has been fully constructed or after the DOMContentLoaded event.įollowing is an example of specifying a loading strategy during script enqueuing: Asynchronous scripts do not have a guaranteed execution order, as script B (although added to the DOM after script A) may execute first given that it may complete loading prior to script A. Scripts marked for asynchronous execution - via the async script attribute - are executed as soon as they are loaded by the browser.Added by specifying an array key value pair of 'strategy' => 'async' to the $args parameter.Deferred scripts are executed in the same order they were printed/added in the DOM, unlike asynchronous scripts. Scripts marked for deferred execution - via the defer script attribute - are only executed once the DOM tree has fully loaded (but before the DOMContentLoaded and window load events).Added by specifying an array key value pair of 'strategy' => 'defer' to the $args parameter.See the sections to follow for more information. This is the recommended method of linking JavaScript to a WordPress generated page.Īs of WordPress 6.3, the new $args parameter – that replaces/overloads the prior $in_footer parameter – can be used to specify a script loading strategy. You could either link a script with a handle previously registered using the wp_register_script() function, or provide this function with all the parameters necessary to link a script. Links a script file to the generated page at the right time according to the script dependencies, if the script has not been already included and if all the dependencies have been registered.
Wp_enqueue_script( $handle, $src, $deps, $ver, $args ) Whether to print the script in the footer.
